Cognism Rate Limits

Cognism publishes numeric API limits in its help centre. What it does NOT publish is the runtime signal: no RateLimit-*, X-RateLimit-* or Retry-After response header is documented anywhere, and none appears in the saved 200 responses of Cognism's own Postman collection. An agent therefore cannot read remaining quota off a response and must back off blind on a 429. Separately from rate limits, volume is governed commercially by the credit pool attached to the subscription — credits are consumed only when a contact is redeemed for the first time.

Cognism Rate Limits is the machine-readable rate-limit profile for Cognism on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, measuring records and redeem-ids.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Sales Intelligence, B2B, Enrichment, Contact Data, and GDPR.

Limits

Search page size per-request
records
20-100
The indexSize query parameter must fall between 20 and 100 records per request.
Redeem batch size per-request
redeem-ids
1-20
One to twenty redeem IDs per redeem call. Larger volumes require multiple requests.
Redeem throughput per-account
records
1000
Up to 1,000 records per minute. The Search API is documented with the same per-minute ceiling.

Policies

Backoff strategy
On 429, reduce request frequency and retry with backoff. Because no Retry-After is returned, use exponential backoff with jitter rather than a server-supplied delay.
Batching
Stay inside the per-request ceilings (100 search records, 20 redeem IDs) and pace redeem batches to stay under 1,000 records per minute.
Spend control
Filter on the preview has* booleans before redeeming. There is no idempotency key, so deduplicate redeemIds client-side to avoid paying twice for a first redemption.
